抄録/ポイント： Mg_17Al_12合金を焼結によって合成し,この合金の水素(H_2)貯蔵特性に及ぼすVとV_2O_5の触媒効果を研究した。結果は,Mg_17Al_12の水素化/脱水素化温度が著しく低下し,可逆的水素貯蔵特性がVまたはV_2O_5の添加により改善されることを明らかにした。例えば,250°Cでは,Mg_17Al_12合金は水素化のみを受け,水素吸蔵容量は2.22wt%であった。しかしながら,VとV_2O_5の添加により,(i)可逆的水素吸収/脱着が起こり,(ii)水素吸収容量は2.95wt%と3.35wt%に増加し,(iii)Mg_17Al_12合金の水素化/脱水素エンタルピーは,それぞれ65.7/83.1kJ mol-1から62.6/69.3kJ mol-1と59.9/68.1kJ mol-1に減少した。Copyright 2018 Elsevier B.V., Amsterdam.
